CircleCI: first layer cache: musl-cross-make+packages downloaded, was still pointing to old musl-cross-make

Browse Source 
First layer cache of CircleCI is reused when second cache is invalidated: that is, to not compiled musl-cross-make from source for x86/ppc64 at each build when any other thing changed under Heads.

Unfortunately, https://github.com/linuxboot/heads/pull/1947 was incomplete in that regard, as showed per build:
- last save cache step https://app.circleci.com/pipelines/github/tlaurion/heads/3270/workflows/07dee00e-926e-4023-b8a7-669078e6ef31/jobs/66483
  - first layer cache saving https://app.circleci.com/pipelines/github/tlaurion/heads/3270/workflows/07dee00e-926e-4023-b8a7-669078e6ef31/jobs/66483

It is also irrelevant to bind first layer cache with .circleci/config.yml, nor Makefile related changes. After all the first layer is related to reusing musl-cross-make to reduce build times on CI
Therefore, only flake.lock and modules/musl-cross-make is relevant to be part of hashed files that should nto change to construct/reuse that cache
